When declaring a variable for a parametrizedparameterized type, it is possible to use wildcards instead of explicit type names. Wildcards are expressed by writing <code>?</code> sign instead of the actual type. It is possible to limit possible types to the subclasses or superclasses of some specific class by writing the <code>extends</code> keyword or the <code>super</code> keyword correspondingly followed by the class name.
